The application link interface in the NTT DOCOMO sp mode mail application 6100 through 6300 for Android 4.0.x and 6130 through 6700 for Android 4.1 through 4.4 writes message content to the SD card during e-mail composition, which allows attackers to obtain sensitive information via a crafted application.

The NTT DOCOMO sp mode mail application 6300 and earlier for Android 4.0.x and 6700 and earlier for Android 4.1 through 4.4 uses weak permissions for attachments during processing of incoming e-mail messages, which allows attackers to obtain sensitive information via a crafted application.

The NTT DOCOMO overseas usage application 2.0.0 through 2.0.4 for Android does not properly connect to Wi-Fi access points, which allows remote attackers to obtain sensitive information by leveraging presence in an 802.11 network's coverage area.

The NTT DOCOMO sp mode mail application 5400 and earlier for Android does not properly verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
